HENRY MAX KUNZ, OF NEW YORK, N. Y.

HOSE-HYDRANT.

SPECIFICATION forming part of Letters Patent No. 609,104, dated August 16, 1898. Application filed December 4, 1897 Serial No. 660,784. (No model.)

To all whom it may concern/.

Be it known that I, HENRY MAX KUNZ, a citizen of the United States, residing at New York, Brooklyn,) in the county of Kings and State of New York, have invented certain new anduseful Improvements in Hose-Hydrants, of which the following is afull and complete specification, such as will'enable those skilled in the artto which it .appertains to make and use the same. I

This invention relates to hose-hydrants of that class which are adapted to be used as fire plugs; and it has for its object to provide a simple and improved hydrant of this character which will provide an effective closure for the hose connection and which will comprise in one mechanism means for opening said closure and conjointly opening the valve.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by the same letters of reference in each of the Views, and in which-- Figure 1 is a vertical transverse sectional view of a hose-hydrant embodying my improvements. Fig. 2 is an elevation of the front of the upper part of the same; and Fig. 3 is an elevation of the upper part of the hydrant, the casing being broken away to show the interior construction.

In the drawings forming part of this specification, A designates a casing which is preferably of cylindrical construction and embodies a top portion adapted to project above the ground 9 and a lower portion extending beneath the ground. The casing may be in the main of any suitable or adapted contour and is provided with a top or cap a, serving to close the top opening, and with a closed bottom, as shown at a. casing may be provided an annular shoulder or flange, as at a adapted to rest upon the ground g and support the casing in position.

B designates the feed-pipe, which enters the lower portion of the casing laterally near 'the'bottom and extends upwardly therein to a point opposite a mouth or opening a located at a convenientpoint in the upper part of the casing. The top end of the upwardlyprojecting or vertical portion of the feed-pipe may be turned outwardly or horizontally, as

of concarb-cpnvex contour and is provided with a central opening.

0 designates a slide which is adapted to normally close the mouth or opening a This slide preferably comprises a plate of suflicient area to fully cover or close the opening a and embodies a topcarrying-arm, as at 0, projecting inwardly and carried upon a tubular rotatable plug D, which corresponds to and is fitted in the opening in the cap a and has an exteriorly-projecting top end d, which is adapted to be engaged by a suitable key or handle in the operation of the hydrant. This exteriorly-projecting end at is preferably of angular contour, adapted to be engagedbya corresponding angular socket in an operating key or handle,and embodies an annular s.houl der d atits base. i E designates a rotary valve-stem which extends vertically and longitudinally within the casing A and has its top end received by the tubular plug D. The plug is provided at its base with a flange CF, and upon the valvestem at a suitable distance below the plug is provided a flange 6, between which flanges d and e is mounted a coiled spring F. The top end 6 of the valve-stem is adapted to engage or interlock with the end (1 of the bore or longitudinal recess of the tubular plug D when the latter is depressed against the tension of the spring F, and for the purposes of this engagement the top end 6' of the valvestem may be of angular construction, adapted to engage the corresponding angular terminal recess at the end of the bore of the plug. Exteriorly upon the Interiorly within the casing A and at the bottom and one side of the mouth oropening a is provided a flange or projection, as at a,

which serves as a limiting-guide in the return of the closure slide or position.

The top portion of the feed-pipe 13 below the horizontal outlet end 6 is preferably flattened or contracted, as shown at b, and said plate 0 to normal flatten ed and contracted top portion may also be flared or widened laterally in approximately fan shape, as shown at 12 Fig; 3, the

purpose of this contracted practically at right angles to the plane of the openings a and widened end portion being to concentrate the jet of water flowing from the pipe and secure greater force or power, as with a nozzle.

The vertical rotary valve-stem E carries upon its lower end a rotary valve H, of any suitable or adapted construction, operating in the horizontal or base portion of the feedpipe 13, and this valve is provided with an extended bottom end, as at h, projecting through an opening in the closed bottom a of the casing and into the top end of a wastepipe I, extending from said opening. The valve is provided in its exterior surface with a vertical groove h, adapted .to communicate with the feed-pipe B and with the waste-pipe I.

The operation and advantages of my invention will be readily understood. When the mechanism is in normal position, the mouth or opening a is securely closed by the slide or plate 0, and the inlet-valve II is also closed. \Vhen thus in normal position, the plug D cannot be depressed to interlock the valvestem E and effect the turning of the same by reason of the fact that the closure-plate O, which is fixed to said plug, engages the bottom portion of the interior limiting-flange a WVhen it is desired to open the hydrant to enable the attachment of the hose to the outlet end of the feed-pipe, it is only necessary to engage the projecting top end d of the plug D with any adapted key or handle and turn the plug sufficiently to throw the closureplate 0 away from the mouth or opening a the relative construction and arrangement being preferably such that a one-fourth part turn of the plug will accomplish this result, when the closure-plate will be free from engagement with the bottom portion of the interior flange 013. The plug can then be depressed by engagement of the key or handle upon the shoulder d, the downward movement of the closure-plate carried by said plug being now permitted to interlock the top end e of the valve-stem with the end d of the bore of the plug, when said plug may be further turned by means of the key or handle, the arrangement being preferably such that another quarter-turn will be sufficient to open the valve H and permit the flow of the water through the feed-pipe B. The depression of the plug D is against the tension of the spring F, which latter will serve to disconnect the interlocking end of the valvestem with said plug D as soon as the pressure upon the latter is released. A reverse movement will serve to return the operative parts to normal position.

It will be seen from the foregoing description that I provide means for successively moving the plate to open the opening in the casing and for opening the valve and for closing said valve and moving the plate to close said opening in the casingthat is to say, the parts are so constructed that the valve cannot be operated while the plate is moving to open or close said opening, but only when the plate stands to one side of said opening.

When the hydrant mechanism is turned to normal position, with the mouth or opening a closed by the slide or plate 0 and the valve II also closed, the groove h will then be in operative position to act as a drain by which the water in the upwardly-projecting portion of the feed-pipe will be drawn off through the valve to the waste-pipe I.

It will be noted that in the improved construction and arrangement as embodied in my invention and herein described the plug D serves the conjoint office of an opening device for the closed mouth of the hydrant and a valve-opener, these movements being accomplished in a relatively successive manner by simply operating the plug as above set forth. It will also be noted that without operation of the rotary and vertically-moving controlling-plug D by means of its key or handle the mechanism is protected against unauthorized or accidental opening of the hydrant or opening of the valvemechanism.

Having fully described my invention, I

claim as new and desire to secure by Letters a casing having a mouth or opening and provided interiorly' with limiting shoulders or flanges arranged with respect to said mouth or opening, a slide or plate adapted to close the opening and operating with respect to said interior flanges so that it engages the same when in normal position, and an operating-plug carrying said slide or plate and provided with an exteriorly-projecting operating end adapted to be engaged by a key or handle, substantially as and for the purpose set forth.
